As a result, some of Earth's angular ( or rotational ) momentum is gradually being transferred to the rotation of the Earth Moon pair around their mutual centre of mass, called the barycentre.

The maximum correction corresponds to the time in which light travels the distance from the barycentre to the Earth, i . e . ?.3 min ( 500 s, 0.0058 days ).

It is isolated from other galaxies, and located near the edge of the Local Group, around from the barycentre of the Local Group the second most remote of all member galaxies after the Sagittarius Dwarf Irregular Galaxy.
14.
The most common dividing line on what is considered a moon rests upon whether the barycentre is below the surface of the larger body, though this is somewhat arbitrary, because it depends on distance as well as relative mass.
15.
It might be within the Hill sphere of another star ( or star group, like Alpha Centauri ), so you'd say it orbited that, and its path would follow an elliptical orbit around that system's barycentre.
16.
Earth and the Moon are nevertheless still considered a planet satellite system, rather than a double planet, because their barycentre, the common centre of mass, is located ( about a quarter of Earth's radius ) beneath Earth's surface.
17.
The illumination provided by a light source that covers a large solid angle is proportional to the cosine of the angle between the surface normal and a sort of barycentre of the light source, so long as all of the source is above the plane of the surface.
18.
The barycentre is always closer to the heavier object ( it's distance to each object in inverse proportion to their masses ), while I think L1 is always closer than the lighter object .-- talk ) 18 : 55, 13 August 2011 ( UTC)

If the two equal bodies rotated about their mutual centre ( barycentre ? ) every 24 hours ( with the plane of rotation in the orbital plane ), they would both have 24 hours days, wouldn't they ? talk ) 22 : 36, 18 August 2008 ( UTC)
20.
A way of thinking of a falling body is that it commences to orbit ( the common barycentre with ) the Earth, usually in a highly elliptic orbit, but in most cases it doesn't get very far because the Earth ( or some other large body ) is in the way.
